   AdSense Auto Ads — collapse slots Google could not fill.

   This is the difference between local and live. Auto Ads injects
   <div class="google-auto-placed"><ins class="adsbygoogle"> between the
   page's blocks, and reserves height for each one BEFORE it knows whether
   an ad exists to put there. When nothing fills, Google marks the slot
   data-ad-status="unfilled" but leaves the reserved height behind — which
   reads as a big empty band between every section. Locally the AdSense
   script never loads, so no slots, no gaps.

   Hiding UNFILLED slots is Google's own documented remedy and costs no
   revenue: there was no ad in them. Filled slots are left completely alone.
